Abstract (en)
[origin: EP1420262A1] The failure detection operates by controlling (76) the switches to form a closed circuit connecting the terminals of the switch to be tested, then generating (78) a current in the closed circuit using a supply connected to the terminals of the converter. The values of a parameter representing current in the electric circuit are then analyzed (80) to deduce failure information.
